An incredibly rich and fine, old silver ore specimen from the mines at Guanajuato, Mexico. This excellent, two-sided specimen features a multitude of beautifully burnished, aesthetically placed on the crest, curved and curled silver wires and silver ropes on a matrix of lustrous, crudely crystallized, solid acanthite. A bonus is olive-green chlorargyrite (close-up) hidden in tiny crevasses on both sides. Old material, mined circa 1930, according to the Jean Behier Collection label. Weighs 54 grams.
